Parsing JSON without Object Mapping in Restkit iOS
ios, json, objective-c, restkit
Solution
You can simply call parsedBody:nil on your RKResponse object and assign the returned object to an NSDictionary:
responseDict = [response parsedBody:nil];
And as an extra check I use a little convenience method to check for a a successful response:
- (bool) wasRequestSuccessfulWithResponse:(RKResponse*)response {
bool isSuccessfulResponse = NO;
id parsedResponse;
NSDictionary *responseDict;
if(response != nil) {
parsedResponse = [response parsedBody:nil];
if ([parsedResponse isKindOfClass:[NSDictionary class]]) {
responseDict = [response parsedBody:nil];
if([[responseDict objectForKey:@"success"] boolValue]) {
isSuccessfulResponse = YES;
}
}
}
return isSuccessfulResponse;
}
Problem
I've created a login page which uses Restkit `RKClient` to send login details, and get back JSON data (either the user or an error). I want to be able to parse the JSON data without object mapping, just JSON to dictionary. The reason for this is it's just a simple login thats sending username and password, if I set up object mapping, i'll have to set up the login details into a Login object, then set up routing etc... and it seem a bit long winded. Here is my code ``` - (IBAction)login:(id)sender { [self.activityIndicator startAnimating]; NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObject:self.username.text forKey:@"username"]; [params setObject:self.password.text forKey:@"password"]; [params setObject:@"login" forKey:@"type"]; [[RKClient sharedClient] post:@"/login" params:params delegate:self]; } - (void)request:(RKRequest*)request didLoadResponse:(RKResponse*)response { if ([request isPOST]) { if ([response isJSON]) { NSLog(@"Got a JSON response back from our POST: %@", response.bodyAsString); } } [self.activityIndicator stopAnimating]; } ``` How can I get the JSON data to a readable object? Thanks
